In accordance with the requirements of the legislation of the Russian Federation on the basis of a complex of pros-pecting works, it is necessary to establish the rate of removal of the soil layer. The thickness of the removal of the soil layer is established on the basis of a complex of laboratory studies of soil samples taken from established soil hori-zons. The thickness of the soil horizons is currently determined using stock data based on the characteristic type of soil. However, the thickness of soil horizons in a number of cases on sections characterized by identical soil characteris-tics differ. Thus, in each specific case it is necessary to link the soil sections and boundaries of the selected soil con-tours instrumentally through ecological excavations. High saturation with soil workings can lead to a significant distur-bance of the soil cover of the surveyed area. To solve the above problem, it is proposed to use a unit for studying the power of multicomponent dynamical systems for vertical drilling of soil wells
